Biochemistry Introduction day 1
... Isotopes: Atoms of an element that have the same number of protons but a different number of neutrons. Ex: Oxygen usually has 8 neutrons but 9 and 10 neutrons can be found in some oxygen atoms. Some isotopes are unstable in the nucleus which makes it more likely to decay and release energy. This i ...

... Atoms bond to satisfy their need for more electrons. If both atoms have high electronegativities (are nonmetals), atoms will share electrons to satisfy the Octet Rule – every atom wants 8 electrons to fill the s and p orbitals in the outer energy level. But, as you will see, if the electronegativiti ...
